Ballmilling Synthesis and Electrochemical Characterization of Ternary Lithium Nitrides

Lithium (transition) metal nitrides were synthesized by the ballmilling technique. The obtained Ni, and Cu) compounds exhibit a high electrochemical activity and reversibility. They could act as high capacity anode materials for lithium-ion batteries. The average capacity of sample prepared in is ca. 880 mAh/g for the first 10 cycles. sample has the smallest capacity about 500 mAh/g with slow capacity fade upon cycling. 78% of its second cycle capacity can be retained at the 50th cycle.
